Acter Group

Acter Group is one of Taiwan's leading cleanroom and facility electromechanical integrators, designing and building the ultra-clean, temperature- and humidity-controlled production environments on which semiconductor fabs, advanced-packaging plants, display, electronic-component, PCB, data-centre and biopharmaceutical factories depend. From its Taichung base the group has grown into a multi-entity "fleet": the parent handles cleanroom, HVAC, industrial ventilation and turnkey facility engineering; Nova Technology supplies water, gas and chemical process-supply systems; 銳澤 specialises in bulk gas and hook-up works; and Shanghai-listed Acter Technology Integration Group serves mainland China. Revenue has roughly doubled since 2021 to a record NT$41.5 billion in 2025, driven by AI-related capacity expansion in Taiwan, CoWoS-type advanced packaging and a breakthrough into front-end foundry facility work. With a record backlog, a 70% dividend payout policy and new subsidiaries in the United States and Japan, Acter is positioning itself as an Asia-origin, globally deployable fab-infrastructure engineering platform.

What the company does

Acter Group designs, procures, builds, tests and maintains the facility systems that make high-technology manufacturing possible. Its core work is the cleanroom envelope and the electromechanical systems inside and around it: make-up air units, fan-filter units, HVAC, exhaust and industrial ventilation, constant-temperature/constant-humidity control, electrical and power distribution, process cooling water, and the "hook-up" connecting tools to utilities. Through its subsidiaries the group extends into process-supply systems — ultrapure water, bulk and specialty gas, chemical delivery and waste-liquid/solvent treatment — allowing it to offer complete turnkey fab-infrastructure packages.

The company describes its principal business as the design and construction of cleroom electromechanical and process facilities for high-technology industries such as electronics and biotech/pharmaceuticals, energy-saving technical services, and electromechanical/HVAC system integration. It lists its service scope as cleanroom engineering, electromechanical and air-conditioning works, industrial ventilation, constant-temperature/humidity engineering, turnkey projects, and repair-and-maintenance services, covering the full cycle from design through construction, testing and validation.

Business and revenue model

Acter is a project-based engineering contractor. Revenue is recognised over time as construction progresses, so reported revenue tracks the physical execution of a backlog of contracts typically spanning one to three years. At end-2025 the transaction price allocated to remaining performance obligations was NT$33,432 million, to be recognised over the following one to three years (FY2025 consolidated financial statements). The broader "orders in hand" measure that management cites — including signed contracts not yet started — reached approximately NT$55 billion at end Q1 2026.

Turnkey / EPC facility projects: Character: Design-build of cleanroom and MEP systems for new fabs and plants; Relative weight: Dominant

Sub-contracted system packages: Character: HVAC, cleanroom, process-supply packages under a general contractor; Relative weight: Significant

Process-supply equipment and systems: Character: Gas, chemical and water systems (Nova, 銳澤); Relative weight: Significant at group level

Retrofit and expansion works: Character: Upgrades of existing fabs, line conversions; Relative weight: Recurring

Maintenance and after-sales service: Character: Repair, maintenance, energy-saving services; Relative weight: Small but stable

Gas materials sales: Character: Gas material sales by 銳澤's innovation business unit; Relative weight: Emerging

The group does not sell subscriptions or licences; its intellectual capital is embedded in design, project-management methods and BIM/EPCM delivery capability.

Value-chain position

Acter sits between the semiconductor/electronics manufacturer (the facility owner) and a long tail of equipment, materials and labour suppliers. It is a tier-one or tier-two facility contractor — awarded packages directly by chipmakers and packaging houses or through general contractors — and acts as the systems integrator that coordinates HVAC, filtration, electrical, piping and controls suppliers into a validated, certified clean production space.

Customer types and end-markets

Customers are, in order of size, semiconductor manufacturers (foundry, memory, OSAT/advanced packaging), green-energy and optoelectronics producers, electronics assembly, consumer/industrial manufacturing, precision industry, and medical/biotech. In 2025–2026 management highlighted semiconductor, electronic components, packaging and testing, PCB, memory and AI supply-chain customers as the main demand drivers, and in Q1 2026 cited AI data centres as an additional source of project activity.

Independent characterisation

Acter is best understood as a high-ROE, asset-light project integrator whose growth is a geared play on fab and advanced-packaging capital expenditure in Taiwan, with China and Southeast Asia as secondary engines and the US and Japan as new options. Historically it focused on smaller sub-contracted packages with tight cost and schedule control; the acquisition of Nova Technology and the formation of a multi-entity group allowed it to bid for larger turnkey contracts. The 2024–2025 entry into advanced-packaging and then front-end foundry facility work for Taiwan's leading foundry marked a step-change in addressable market and is the main reason revenue and margins reached record levels in 2025–2026.

Stated strategy

Management describes its competitive advantages as "internationalisation, differentiation and diversification" and its goal as becoming an international-grade engineering service platform. Its strategic priorities include:

Market expansion and investment efficiency: Content: Deepen existing relationships, win new customers, expand overseas, pursue vertical specialisation and horizontal integration

International cooperation and technical services: Content: Work with international partners on semiconductor equipment R&D and cybersecurity; help customers build smart facilities

New engineering and environmental technology: Content: Combine gas/chemical supply expertise with waste-liquid and solvent treatment to develop green engineering and energy services

Talent and management development: Content: Recruit multi-disciplinary talent and build the next management cohort

Project-management excellence: Content: Shorten completion times, raise order-conversion rates, handle rush orders, raise output per employee

Medium-term guidance

Management does not publish numerical revenue or margin targets. Its qualitative outlook for 2026 is positive, citing AI, semiconductors, electronic components, PCB and memory investment, and a goal of raising output per employee as order volumes scale.
